SLD (Single Line Diagram) shows the electrical connections from substation to room light.

• Start with the substation as the power source

• Draw a line representing the main distribution line

• Include transformers, panels, switches, and cables

• End with the room light as the final destination

A bug is an issue or defect in a software application that causes it to not work as intended.

• Bugs can range from minor issues like typos to major problems like crashes or data loss

• Examples of bugs include incorrect calculations in a financial application, broken links on a website, or a login form not working properly

Regression testing is testing the entire application after changes, while retesting is testing a specific bug fix.

• Regression testing ensures that new code changes do not affect existing functionality

• Retesting focuses on verifying that a specific bug fix has been successfully implemented

• Regression testing is done after every code change, retesting is done after a bug fix

• Regression testing involves running a full suite of tests, retesting focuses on the specific test case relat...read more

SP stands for Schedule Performance, TPN stands for Total Planned Value, VTPN stands for Value of Total Planned Value

• SP is a measure of how well the project is adhering to the schedule

• TPN is the total budgeted cost of the work scheduled to be done

• VTPN is the earned value of the work actually completed

Corrective Action and Preventive Action are two types of actions taken to address and prevent issues in a process or system.

• Corrective Action is taken to address an existing issue or problem in a process or system.

• Preventive Action is taken to prevent potential issues or problems from occurring in a process or system.

• Examples of Corrective Action include investigating the root cause of a defect and implementing a solution to prevent it from happening again.

• Examples of Prevent...read more

Distribution boxes are used to distribute electrical power to different circuits or devices within a building.

• Distribution boxes can be categorized based on the number of ways or circuits they can accommodate (e.g. 4-way, 8-way, 12-way)

• They can also be classified based on the type of protection they offer (e.g. MCB distribution box, RCCB distribution box)

• Distribution boxes can be surface-mounted or flush-mounted depending on the installation requirements

The type of wire flexible depends on the material used and the intended application.

• Different types of flexible wires include silicone wire, PVC wire, and Teflon wire.

• The flexibility of a wire can be determined by its strand count and gauge.

• Flexible wires are commonly used in industries like electronics, automotive, and robotics.

Copper is the most commonly used material in wire due to its high conductivity and affordability.

• Copper is the most common material used in wire due to its high conductivity and affordability

• Other materials used in wire include aluminum, silver, and gold

• The choice of material depends on the specific application and requirements

Copper wiring typically uses copper with high conductivity, such as copper with a purity of 99.9% or higher.

• Copper wiring commonly uses high-conductivity copper, such as ETP (Electrolytic Tough Pitch) copper.

• Copper wiring may also use OFHC (Oxygen-Free High Conductivity) copper for applications requiring high purity.

• Copper wiring with a purity of 99.9% or higher is often preferred for electrical conductivity.

• Different types of copper wiring may be used based on specific requi...read more

Various tools and statistical methods are used depending on the scenario.

• Tools: Excel, Tableau, Power BI, SQL, Python, R

• Statistical methods: Regression analysis, hypothesis testing, clustering, decision trees

• Scenario: Sales forecasting, customer segmentation, process improvement

• Tools and methods are chosen based on data availability and business needs

The type of wiring used depends on the specific project requirements and regulations.

• Consider the voltage requirements of the project

• Choose between solid or stranded wire based on flexibility needs

• Select the appropriate wire gauge for the current load

• Follow local electrical codes and regulations

• Examples: THHN wire for general wiring, Cat6 cable for networking projects

Layers of cable refer to the different levels of insulation and protection surrounding the core conductor.

• Layers of cable provide insulation and protection for the core conductor.

• Common layers include conductor, insulation, shielding, and jacket.

• Examples of cables with multiple layers include coaxial cables and Ethernet cables.

The Power triangle is a diagram used in project management to illustrate the relationship between scope, time, and cost.

• The three sides of the triangle represent scope, time, and cost.

• The triangle shows that changes in one aspect will affect the other two.

• For example, increasing the scope of a project will likely lead to an increase in time and cost.

• Conversely, reducing the time allocated to a project may require a reduction in scope or an increase in cost.

CAPA stands for Corrective and Preventive Action. It is a process used to identify and address problems to prevent their recurrence.

• CAPA is a systematic approach to problem-solving that involves identifying the root cause of a problem, implementing corrective actions to address the immediate issue, and taking preventive actions to prevent the problem from happening again.
